Modern PCs are certainly marvels of technology--and yet for all their advances,
computers still do crazy, inexplicable things. With the average machine, there's
enough mystery to keep Sherlock Holmes or Miss Marple hopping for a month--and
enough frustration to make the average user want to commit murder most foul.
Computing mysteries tend to be less "Who dunnit?" and more "Why won't it?"
For example, you may have puzzled over why Windows obstinately refused to let
you delete a stalled print job, or wondered why you couldn't find the file you
just downloaded. But worry not: We've rounded up these and other mindbogglers of
the PC universe--and solved them for you.
(For explanations and helpful tips, click the links.)
Where did my downloaded files go? Why can't I
find them?
Your browser
chooses where downloads go, but you can control the process.
Why doesn't my iPad charge when I connect it
to my computer?
Your PC's USB
port doesn't supply enough juice--but you can still charge your iPad,
gradually.
Why does a video play on my desktop but not
my laptop?
If a computer doesn't have the specific
decoder for a video format, you can't watch the video. Get the right
one.
My printer won't print, and Windows won't allow me to
cancel or delete print jobs. What's going on?
Usually this is the result of a communication
problem between the PC and printer. Get them talking.
I hear beeps when I turn on my PC. What do
they mean?
Those beeps come from the BIOS (a piece of software built into the
motherboard). Find
out what a "beep code" means.
In a folder full of digital images, I often
notice a file called Thumbs.db. What is it, and can I safely delete it?
Thumbs.db is a Windows XP system file that contains the thumbnail
cache for a particular folder. You can tweak Windows to get it out of your
way.
Why does every digital camera--even the one
on my smartphone--insist on storing photographs in a folder called DCIM?
DCIM (for Digital Camera
IMages) is the default directory structure for digital cameras--and having
such a standard is very useful.
My Recycle Bin has disappeared. How do I go about
restoring it?
Whether it was a victim of a glitch or never available in the first place,
you can follow a few simple
directions to restore the Recycle Bin.
Why does Windows sometimes reboot without my
permission, and how do I prevent that from happening?
This problem relates to how
Windows installs automatic updates. Fortunately, you can make some
tweaks.
Where do all these mysterious Web browser
toolbars come from, and how do I get rid of them?
Sometimes spyware
installs browser toolbars, and sometimes you do it accidentally during
software installation.
How did I end up with QuickTime on my PC, and
do I need to keep it?
This media-playback software comes bundled with
iTunes and installs along with it.
I have Microsoft Word installed on my PC. Why
can't I open the .docx files my friend sent me?
If you use Word 2003 or an earlier version of the program, all you need is
the Microsoft
Office Compatibility Pack for Word, Excel, and PowerPoint 2007 File
Formats.
Why won't Windows allow me to delete a certain file?
If Windows refuses to delete a file or folder, some application or
process is accessing it.
Why do some programs leave files and folders
behind even after I've uninstalled them?
Many programs' uninstallers are ineffective. Use a utility that removes not
only the application but also all of the
pieces it leaves behind.
Why do Adobe Reader and Java update so
frequently? Do I have to allow it?
Most Adobe
and Java patches are made to plug security holes, so you should update
them--or use alternative software.
Is it absolutely necessary to update
Windows?
Yes, you should definitely apply
Windows updates for security reasons, but you can take a few steps to cut
down Windows' nagging.
Does it matter whether I ‘Safely Remove'
devices?
Absolutely: If you ignore Windows' requests to "Safely Remove" your storage
media, you could end up with corrupted files,
unreadable media, or both.
Windows asks me if I want to enable Sticky
Keys. What are they, and how should I use them?
The Sticky Keys
feature makes certain keyboard functions easier to access.
Why can't I send out a particular file
attachment through e-mail?
The file is probably too large. Check out free services that let you
work around file-size restrictions.
How can I determine whether an unknown Website is safe to
visit?
Read our suggestions on figuring out
whether a link is safe from malware or other threats before you click
it.
What are the .dat files I sometimes receive
in e-mail messages, and how do I open them?

fonts and the like, but it often causes problems for the recipient. We have three
suggestions for coping.
